MACHINE FOR DROPPING POWDERED FUSlBLE MATERIAL UPON HOT GLASS OR METAL.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed December 1, 1905 I serial. No. 289,897-

1'0 all whom it may concern.-

Be it known that I, WILLIAM B. NORTON, a

citizen of the United States, residing at Detroit, county of Wayne,State of Michigan, have invented a certain new and useful Improvement inMachines for Dropping Powdered Fusible Material upon Hot Glass or Metal;and I declare the following to be a full, clear, and exact descriptionof the illvention, such as will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to a machine for dropping powdered fusiblematerial upon hot glass or metal for the purpose of ornamenting thesame.

The glass or metal object in a hot condition is presented at the properplace in the machine and powdered fusible glass that fuses at atemperature so low that it will adhere to and fuse onto the hot articleis used in the form of a powder and is shaken through a stencil orseries of stencils arranged to allow the powder to fall directly tothose places where it is to adhere. The stencils are held in such closerelation to the heated article that the falling powder retains thegeneral outline of the stencil through which it is delivered and fallsupon and fuses onto the article, retaining the ornamental configurationof the stencil.

The invention is used mainly to produce lettering on the heated article;but it may be used for any ornamental character or figure.

In the drawings, Figure 1 is a perspective of the machine. Fig. 2 isaperspective showing the side reverse to that shown in Fig. 1. Fig. 3 isa plan with some parts broken away. Fig. 4 shows a detail of anair-valve. Fig. 5 is a cross-section through the stencil-sieve.

A indicates the base of the machine, provided with adjustable plates 1,2, and 4, all of which are held to the base adjustably to form a cage orguide in which the article to be treated will be brought accurately toplace under the stencil. These are held to the base by set-screws 11,21, 31, and 32. The foot-plates 12 and '33 are pivotally secured to theplates 1 and 2 by lugs 34 and 35 on said plates 1 and 2, so that theplates 1 and 2 may be adjusted with an angular opening between them ifthat position of adjustment be desired because of the shape ofthearticle to be treated. The plate 4 is an end abutment whose positionis regulated by a screw 41, that is fixed to the plate and is axiallymoved by nuts 42 and 421. The nuts are held from axial movement by a lug43. At each end of the machine there is a post. The post 5, which risesat the rear of the machine, has vertically movable on it a hingeblock51, held by set-screw 52 and having hinged to it arms 53 of a fork,which carries a frame 34. The hinge-block 51 supports a post 55. Atension-spring 57 connects the top of the post 55 to an car 56 on theframe and serves to normally lift the handle end of the frame 54. Theframe 54 is a rectangular frame, open at the bottom and provided with acover 45. In this rectangular frame is inserted a removable box 43,which is provided with a stencil-bottom. At about the center of thecover 45 is attached a pneumatic hammer or rapper 46, actuated by airthat is introduced through air-pipe 47. The hammer serves to rap theframe and box 43 and the stencil and to shake powder from the box 43through the stencil. The shaking takes place only when the handle 35 hasbeen pressed down against a stop-bracket 36, that is supported by a post37, which rises from the frame A at the front thereof. The post 5, asshown, is slabbed off or prismoidal to prevent the frame from swingingin a horizontal plane with respect thereto, and the post 37 is eitherslabbed off or, as is shown, provided with a groove 38, in which engagesan inward-extending projection from the bracket 36 in order that thebracket and the parts intimately connected with it may retain theirproper relation with respect to the frame. The bracket 36 includes avalvecasing 39, to which is connected an air-pipe 47, which leads to thehammer 46.

depressed and brought to its rest on the bracket 36. In making thisswing to the right a hook 27 on the handle engages the head of avalve-stem 28, and the air-controlling valve 29 is operated to open theorifice through which the air passes by swinging the handle 35 to theright and pushing the valvei Connected to the valve-casing is a gage 25and a stem 28 into the casing against the tension. of springs and 90.Thus the operator by a continuous movement of one hand swings the screento place and opens the air-valve which then begins to actuate thepneumatic hammer 46. A lock-pin or steady-pin 91 extends to the frontand engages between two pins 92 93, that project upward from the bracket36. The handle remains on the rest a sufficient length of time. Then theoperator lifts or releases the handle, and after moving the han- (lle tothe left the handle and frame are lifted by spring 57. The air-valve 29automatically closes by following the movement of the handle to theleft.

At the rear of the machine, supported by the bracket 51, is avalve-casing 62, with. a valve that is actuated by the arm 53, whichengages against the projecting head 63 of the valve and opens theorifice of the air-passage from air-pipe 64. The air-pipe 65, whichlatter terminates with a nozzle 66, lies to the rear of and slightlybelow the frame. The nozzle 66 is provided with a row of j et-holes thatproduce blasts of air across the bottom of the stencil-box 43, whichkeep the stencil cool, preventing the fusing of powder in the stencil.

The stencil is of fine wire between two plates 481 and 432, which platesform a bottom to the box 43, that is impervious except where openingsare cut through the plates. There is an opening, as 432, in the bottomplate 432 and an opening, as 431, in the top plate 431, both of whichregister and form an opening to the entire box-bottom filled with finescreen-wire.

On the handle side of the machine and between the main part of the frameand the valve-stem 28 is a guard 281, that is located higher than thestem 28 and projects to or slightly beyond. the end of the stem 28 whenit is in the position shown in Fig.4. The handle 35 is provided with ahook 27, that engages against the stem. 28, and with a projectionextending from the hook that engages under the projection 281, andbefore reaching the position of contact between the hook 27 and thestem. the hook projection 282 engages against the overhanging projection281, which thus guards the parts from accidental engagement before theentire frame which carries the boxis completely down on its seat. Afterthe box has reached this position the projection 282 engages under theoverhanging projection 281 and holds the parts locked in position duringall the time that the air-motor is in operation.

The swing of the handle on its pivot 271, which takes place when thehandle is clearing the projection 281 and again when it is man uallyforced into engagement with the stem 28, occurs at a time when thesteady-pin. 91 is in engagement between the two pins 92 and. 93 and thisswing of the handle is without actuating influence on the box ofpowdered material.

In using this machine the several holding and steadying parts areproperly adjusted to correspond with the article upon which the ornamentis to be fused. The article in a hot condition is placed in the machinebetween the guides 1, 2, and 4 on the form or tool for handling, whereit is held by the workman, who grasps the handling implement with onehand to hold the article in position and grasps with his other hand. thehandle 35 and swings the stencil-box to place. In this operation theworkman opens the air-valve and admits air to the pneumatic hammer,which raps the receptacle and shakes out therefrom a quantity ofpowdered material that drops upon the hot metal and is fused thereon. Ifthe hot metal be glass, the ornamental mate rial is fused into the bodyof the glass to a slight extent but for the most part it lies 011 thesurface in a raised figure, conforming to the opening through thestencil-plate.

What I claim is 1. A machine for ornamenting metal, consisting of asteadying-frame for the article to be ornamented, a receptacle for theornamenting material pivotally supported there by, a stencil-plateforming the bottom closure for the receptacle, and means adapted to beactuated by the engagment thereagainst of said. receptacle whereby thesame is caused to vibrate, substantially as described.
